This is a stupid test and doesn't test whether you have the right amount of confidence in your knowledge in a sensible way. Take this example:

"Wilt Chamberlain was shorter than 7 feet"

I mean, I have no idea really, but most people are well under 7 feet tall aren't they? So really I'm answering on the basis of what I think the psychology of the questioner is, rather than anything else.

This is likely to have very little correlation with how people behave in their lives when it comes to over- or under-stating their confidence in their assertions.
